Solution Overview

Problem

Existing autonomous driving systems face challenges in handling edge cases, particularly in complex environments, and rely on remote human operators who are prone to errors due to fatigue, distraction, and communication latency, which can lead to delayed responses in critical situations.

Innovation Solution

A collision warning system that calculates dynamic trajectories of vehicles based on sensor data, accounts for latency and operator reaction time, and generates overlays to visualize risks, allowing remote operators to make informed decisions while prioritizing automated collision warnings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If remote human operators are used to handle edge cases, then the ability to handle complex environments improves, but human error and response delays increase

Engineering Contradiction:
Improveability to handle edge casesVSAvoidresponse reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system introduces an intermediary automated collision warning system that acts as a mediator between the remote operator and the vehicle. This intermediary provides real-time collision warnings and trajectory overlays to the operator, enhancing their decision-making capability while maintaining the benefits of human judgment for edge cases.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements continuous feedback by calculating dynamic trajectories in real-time and providing collision warnings to the remote operator. The feedback loop includes receiving sensor data, computing risk trajectories, displaying warnings, and adjusting based on operator responses, thereby improving response reliability without eliminating human oversight.

Inventive Principle:
Principle #23Feedback

2Productivity

If remote operators monitor multiple vehicles, then system productivity improves, but operator orientation and decision accuracy deteriorate

Engineering Contradiction:
Improvevehicles monitored per operatorVSAvoidsituation awareness accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system segments the complex monitoring task by providing separate, dedicated collision warning overlays for each vehicle. Each operator interface displays trajectory-specific information for individual vehicles rather than requiring holistic mental models of multiple complex situations, thereby maintaining precision while increasing productivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-calculating dynamic trajectories and identifying potential collision risks before the operator needs to make decisions. This advance preparation of trajectory information reduces the cognitive load during critical decision moments, allowing operators to maintain accuracy even when monitoring multiple vehicles.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If passive warning systems are used, then system complexity remains low, but collision avoidance effectiveness is limited

Engineering Contradiction:
Improvesystem architecture simplicityVSAvoidcollision avoidance capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system transitions from static warning thresholds to dynamic trajectory-based warnings that adapt in real-time to changing vehicle conditions, speeds, and environmental factors. This dynamic approach maintains relatively simple system architecture while significantly improving collision avoidance effectiveness through context-aware risk assessment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system adds a new dimension to traditional warning systems by incorporating temporal trajectory projections rather than just spatial proximity alerts. By visualizing future collision paths and risks over time, the system enhances collision avoidance capability without requiring fundamentally complex architectural changes.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
